Hi i have search on Umbraco 7 and it works OK, but i have to add a lot of search fields to index and it´s not practic. How can i search through all fields instead of adding them manually?

@{
    string searchQuery = Request["query"];
    if (String.IsNullOrWhiteSpace(searchQuery))
    {
        searchQuery = "";
    }

    var searcher = ExamineManager.Instance;
    var searchCriteria = searcher.CreateSearchCriteria();

    var query = searchCriteria.GroupedOr(new[] { 
    "nodeName", 
    //"packSizes",
    "name", 
    "title", 
    "bodyText", 
    "body",
    "field1",
    "field2",
    "field3",
    "field4",
    "field5",
    "field6" 
     }, searchQuery).Compile();
    var SearchResults = searcher.Search(query).Where(x => x["__IndexType"] == "content").ToList();
}
@if (SearchResults.Any())
{
    <ul class="search-results-box">
        @foreach (var result in SearchResults)
        {
            var node = Umbraco.TypedContent(result.Id);
            var pathIds = result["__Path"].Split(',');
            var path = Umbraco.TypedContent(pathIds).Where(p => p != null).Select(p => new { p.Name }).ToList();

            if (node != null)
            {
                <li><a href="@node.Url">@node.Name</a></li>
            }
        }
    </ul>
}
